Foam Roof Failure in Scottsdale
When Poor Installation Leads to Costly Damage
We responded to a serious foam roof failure in Scottsdale caused by strong winds. The wind lifted half of the roof right off, exposing the home to potential leaks and costly interior damage. A properly installed foam roof should never detach like this, which led us to investigate the root cause. Unfortunately, it became clear that improper installation was to blame.
This is a cautionary tale for homeowners - A foam roof is only as good as its installation. When done correctly, it can last for decades, providing energy efficiency, seamless waterproofing, and durability. But when shortcuts are taken during installation, the consequences can be disastrous.
What Went Wrong? The Dangers of a Poorly Installed Foam Roof
Foam roofing is one of the best roofing solutions for Phoenix homes because of its seamless waterproof barrier and energy-saving insulation. However, in this case, the original installation was not done correctly, leaving the roof vulnerable to wind damage. Here’s what we found:
🔹 The foam wasn’t properly prepped and adhered to the surface. Spray foam roofing requires meticulous surface preparation to ensure full adhesion. Any dust, dirt, or moisture on the substrate can prevent the foam from bonding correctly.
🔹 There were unsealed gaps where air and water could seep underneath. When foam is applied correctly, it expands to create a continuous, monolithic layer. In this case, improper application left weak spots where wind could easily get underneath.
🔹 Lack of regular maintenance and recoating. A foam roof requires an elastomeric coating every 5 years to maintain its protective barrier. If recoating is neglected, the foam becomes brittle and vulnerable to the elements.
As a result, when strong winds hit the area, air was able to get under the poorly adhered sections, causing the roof to peel up and detach completely.
How a Properly Installed Foam Roof Should Perform
A well-installed foam roof is one of the most durable and long-lasting roofing options available, especially in the Arizona climate. When done right, it:
✅ Forms a seamless, waterproof barrier that eliminates weak points and potential leak areas.
✅ Fully adheres to the substrate, preventing wind uplift and ensuring a strong bond.
✅ Provides superior insulation, reducing energy costs by reflecting heat away from the home.
✅ Lasts 40+ years with proper maintenance and timely recoating.
Signs Your Foam Roof May Be at Risk
If your foam roof was not installed by an experienced professional, it could be at risk of premature failure. Here are some warning signs that indicate potential problems:
❗ Blisters or bubbles forming in the foam – This means air or moisture is trapped beneath the surface.
❗ Cracks or peeling in the elastomeric coating – The protective layer is failing, leaving the foam exposed.
❗ Soft or spongy areas – This could mean the foam has weakened due to improper installation or aging.
❗ Discoloration or chalky texture – A sign that the roof is drying out and losing its protective barrier.
If you notice any of these issues, it’s important to schedule an inspection before major damage occurs.
How to Protect Your Foam Roof from Failure
The best way to ensure your foam roof remains strong and durable is to follow these steps:
- Choose a Reputable, Experienced Roofing Contractor
Not all roofing contractors have the expertise to install foam roofing correctly. Make sure you work with a licensed, experienced professional who specializes in spray foam applications.
- Get Your Foam Roof Inspected Annually
Regular inspections help catch small issues before they turn into expensive repairs. A professional can check for cracks, blisters, and adhesion issues that may indicate installation problems.
- Recoat Your Foam Roof Every 5 Years
An elastomeric recoat is essential for protecting the foam from UV damage, moisture, and deterioration. Neglecting this step can shorten the lifespan of your roof and lead to costly replacements.
- Address Repairs Immediately
If you notice peeling, soft spots, or water pooling, schedule repairs as soon as possible to prevent further damage.
